Summary:X-ray, IR-spectroscopic and electron-microscopic studies were conducted with the use of modern techniques. Moreover, the estimation of acid-base properties of the obtained (due to developed technique) solid solutions of ZnTe – CdSesystem was undertaken as well. They have been certified as the solid substitution solutions with a sphalerite or wurtzite structure depending on the composition. The ultimate composition, the average particles size, specific area and acid areas strength (pHiso) were determined. Some definite laws were found in bulk and surface properties changes. Specialattentionshouldbepaidtotheextreme, secularlyreflectedchanges of the number of the definite sized particles and pHiso, which are logically predetermined by the coordinative unsaturation change of the surface atoms as the active sites. Thesolidsolutionsofthe “extremecompositions” are recommended for production of rapid-response analyzers for the basic gases micro-impurities.
